After learning of the lies and deceits that Casey spews, I do think she could easily have put a drugged Caylee in the car / trunk during the last few weeks of her life. The back seat of her car opened into her trunk, and I've wondered if the "air mattress" could not have served a dual purpose. She could have easily been knocking her out,even with overOTC benadryl /diphenhydrmine, to be able to party hearty her nights away. As a nurse, I have tried to look closely at Caylees eyes and facial coloring in her later photos. The dark circles around her glassy ( at times) eyes, and discoloration around her mouth concerned me. If the windows were cracked, the car would not have been that hot at night. I also wondered about her " leaving the room" for phone calls was not an excuse for her to go & check her car. These are purely speculations on my part, but given the duct tape horror,I do think she was quite capable of this, so I voted yes.
No drugs in Caylee's hair.
Caylee wouldn't have survived even an hour in KC's car trunk in the summer. If Caylee was locked in the car she could have popped up and been seen. She would have screamed unless gagged. Duct tape over her mouth would have pulled skin off when removed.
And besides, before Tony, KC didn't need a babysitter. Until May 25 and the "No Clothes Party" KC was able to get Cindy to babysit by saying she had to "work". There is testimony & pictures that show sometimes KC brought Caylee along to parties.
Ricardo tolerated sharing his apartment and bed with Caylee. KC was with Ricardo the VERY morning of the day KC declared Tony her official boyfriend. It isn't like KC went through any dry spells between men.
KC was officially with Tony a whole 6 days before she killed Caylee.
